Based on aerodynamics and fuel efficiency design. Nasa and Boeing are studying a concept design named Transonic Truss-Braced Wing (TTBW), belonging to the Subsonic Ultra Green Aircraft Research program. Boeing has a configuration with an outstanding aerodynamic flying within Mach 0.70 – 0.80 (Transonic), a competitive speed similar to airliners. The wing plane comprises a […]
